摘要： A water heater control modifies a temperature differential setting in a hot water heater according to elapsed time between calls for heat. This allows the temperature setting of the hot water heater to remain low, which reduces the risk of scalding, yet allows the hot water heater to deliver hot water consistently. For example, a hot water heater temperature setting is 120.degree. F. and the temperature differential is normally set to 20.degree. F. After six hours without a call for heat, during which time period the water in the tank has destratified, the water heater control could set the differential to 15.degree. F., which would cause a call for heat when the water temperature drops to 105.degree. F. Once a call for heat is generated, the temperature differential can be set back to 20.degree. F. Thus, water stratification is reduced because a wide temperature differential is maintained during periods when there are repeated calls for heat, but cool water is avoided because the differential is narrowed during periods of inactivity.
摘要翻译：热水器控制根据热量呼叫之间的经过时间修改热水器中的温差设置。这样可以使热水器的温度设定保持在低温状态，从而降低烫伤的风险，同时允许热水器一贯地输送热水。例如，热水加热器的温度设定为120°F，温差通常设定在20°F。六个小时后无需加热，在此期间罐内的水已经脱水，热水器控制可以将差值设定为15°F，当水温降至105°F时，会产生热量。一旦产生热量呼叫，温差可以恢复到20°F。因此，水分层减少，因为在反复要求热量的时期内保持较宽的温差，而避免冷水由于差异在不活动期间变窄。

摘要： A test circuit for testing operation of a liquid level detector. The liquid level detector includes a probe that is placed at a test site. A control circuit monitors changes in capacitance of the probe due to changes in the liquid level at the test site. A test switch grounds an input to the probe which and causes the control circuit to sense an alarm condition. If the detector does not activate an alarm when the test switch is actuated, the detector is not properly functioning and repair or replacement of the level detector is needed.
